Conformable sand screen
A sand control tool including a base pipe having a radial port through a wall thereof, a plurality of volume increasing members disposed upon the base pipe, a filtration segment disposed upon the base pipe and disposed between and in physical contact with ones of the plurality of members, and a cover disposed radially outwardly upon the plurality of members and plurality of segments. An embodiment of a sand control tool including a base pipe having a radial port through a wall thereof, a volume increasing member helically disposed upon the base pipe, a filtration segment helically disposed upon the base pipe adjacent the member, and a cover disposed radially outwardly upon the member and segment.
NON-METALLIC COMPLIANT SAND CONTROL SCREEN
A sand screen apparatus for use in a downhole operation for hydrocarbon recovery includes a non-metallic material and a mechanical retainer. The non-metallic material has a compressed state and an expanded state, and includes a base polymer, and one or a plurality of smart fillers dispersed with a polymeric matrix of the non-metallic material. The mechanical retainer compresses the non-metallic material in the compressed state. The one or the plurality of smart fillers react with the base polymer in the expanded state after exposure to a wellbore condition.
BUOYANCY ASSIST TOOL
A buoyancy assist tool has an outer case and a sleeve disposed in the outer case. The sleeve is movable from first to second positions in the outer case. A permeable membrane is attached to the movable sleeve at a lower end thereof. A rupture disk is mounted in the outer case. Fluid flow through the permeable membrane detaches the sleeve from the outer case and moves the sleeve from the first to the second position. In the second position, the sleeve creates an open bore for the passage of downhole tools therethrough.
FILTRATION MEDIA INCLUDING POROUS POLYMERIC MATERIAL AND DEGRADABLE SHAPE MEMORY MATERIAL
A fluid control device includes a support structure configured to be deployed to a selected location in a borehole, and a filtration medium disposed at the support structure and configured to filter a fluid, the filtration medium configured to be compacted from an initial shape to a compacted shape prior to deployment in the borehole. The filtration medium includes a first polymeric material configured to withstand a temperature at the selected location, the first polymeric material forming a porous structure including a plurality of fluid passages, and a second polymeric material including a shape memory polymer disposed within the fluid passages, the shape memory polymer configured to expand in the plurality of fluid passages and cause the filtration medium to expand in the borehole.
COMPOSITIONS AND METHODS FOR USE OF PROPPANT SURFACE CHEMISTRY TO IMPROVE PROPPANT CONSOLIDATION AND FLOWBACK CONTROL
The present invention relates to methods for hydraulically fracturing a subterranean formation to improve the production rates and ultimate recovery by contacting unconsolidated resin-coated proppant particulates residing in a propped fracture with a reactive crosslinker in order to form a consolidated proppant pack. The present invention also relates to methods for use in water injection wells to consolidate the resin-coated proppant particulates in a gravel packed or frac packed region of a wellbore.
FILTRATION OF FLUIDS USING CONFORMABLE POROUS SHAPE MEMORY MEDIA
A fluid control device includes a support structure configured to be deployed in a borehole, and a filtration component disposed at the support structure, the filtration component including a porous medium made from a thermoplastic polymer material, the porous medium including an open cell foam. The porous medium has a porosity selected to cause the porous medium to exhibit shape memory behavior, and the porous medium is configured to be compacted from an initial shape to a compacted shape, deployed in the borehole, and subsequently expanded due to a downhole temperature to conform to a surface of the borehole.
EPOXY-BASED FILTRATION OF FLUIDS
A fluid control device includes a support structure configured to be deployed in a borehole and a filtration component disposed at the support structure. The filtration component includes a porous medium made from a shape memory epoxy, the shape memory epoxy including a soft segment monomer and a hard segment monomer, the porous medium configured to be compacted from an initial shape to a compacted shape, deployed in the borehole, and subsequently expanded due to a downhole temperature to conform to a surface of the borehole.
Expandable liner and method for running the same
An expandable liner and a method for running the same including a base pipe, wherein the base pipe is provided with a passage extending through an axial direction of the base pipe, a connection structure disposed at both ends of the base pipe, and screen openings on a wall of the base pipe; a porous expandable layer is fixedly attached to an exterior of the base pipe and made of a non-memory formed and compressible material. The expandable liner and the method, by adopting a non-memory porous expandable layer, realize a sand-control performance and a wellbore-supporting capability of a technology where memory materials are used in manufacturing, operating and running.
System and method to calibrate digital rock wettability
A method is provided. Cells of a digital model of a formation are classified corresponding with one or more classes based on minerals and/or pore sizes. Wettability of the formation in the digital model is calibrated based on imbibition and/or drainage curves from physical experimentation for a rock sample and the one or more classes of the cells of the digital model.
Crosslinked synthetic polymer-based reservoir drilling fluid
A wellbore fluid includes a base fluid; and a crosslinked and branched polymeric fluid loss control agent formed from at least an acrylamide monomer and a sulfonated anionic monomer; wherein the fluid loss control agent has an extent of crosslinking that is selected so that the fluid loss control agent has a viscosity that is within a peak viscosity response of the viscosity response curve.
